PIPE-COVERING.

SPECIFICATION formingpart of Letters Patent No. 754,256, dated March 8,1904.

Application filed August 3, 1908- TO all whom it may concern.-

Be it known that I, MAURICE SULLIVAN, a citizen of the UnitedStates,-and a resident of the city of New York, borough of Brooklyn,

' in the county of Kings and State of New York,

shield which itself carries the asbestos or other compound forming thenon-conducting covering.

This specification is a specific description of one form of myinvention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is an elevational view of a cross or four-way pipe connectionwith the frame of my improved covering applied thereto. Fig. 2 is a sideelevation of a simple joint, showing the frame of my improved coveringapplied. Fig. 3 is an elevational view of an elbow connection, showingthe frame of my improved covering applied. Fig. 4 is an elevational viewof a valve or gate having the frame of my covering applied. Fig. 5 is afragmentary perspective view showing parts of the frame, shield, andcovering proper; and Figs. 6, 7, and 8 are detail views illustrating thevarious parts of the framing.

The simplest form of the invention is illustrated in Fig. 2, in whichtwo clamps are provided, one on each side of the joint. Each clamp isformed of two sections such as shown in Fig. 6, these sectionscomprising a semicircular body part a, with ends a projecting Serial No.168,012. (No model.)

therefrom. Said sections are formed, preferably, of cast metal angularin cross-sectional form. The two sections of the clamp are made toembrace the pipe, with their end portions a lying alongside of eachother, thus forming the clamp, and the two clamps are formed bylongitudinal members each formed of two sections 6, such as shown inFig. 7 These sections consist of metal cast in angle-iron form and laidside by side. Each section is provided with an upwardly-extending lug 6,formed with a slot or recess, through which is passed a fastening-bolt0, thus connecting the two sections rigidly together and forming thelongitudinal connecting member. Said members are fastened to the clampsby means of bolts (2, located at the ends of the longitudinal connectingmembers.

Fig. 5 shows one half of the structure above described, the other halfbeing the same as shown in Fig. 5 and being bolted thereto through themedium of the bolts 0 and lugs b, as before described. Fastened to eachof the members a and b is a semicircularshield e, of woven wire orsimilar material, which is formed so that it incloses the pipe-joint. Onthis shield is molded by any suitable means the asbestos or othernon-conducting covering f. It will thus be seen that when the framing isfastened in place as shown, said framing having the shield e andcovering f previously applied thereto, a complete nonconducting coveringis provided for the joint. This enables the pipe-covering proper to beplaced on the pipe and abutted against the sides of the joint-covering,thus forming a complete covering for the pipe and its joints.

By means of this improvement the covering for the joint may be removedat any time by disconnecting the bolt 0 without in any Way disturbingthe covering of the other parts of the pipe. This enables the joint tobe reached at will, and it avoidswhat has heretofore been frequentlynecessarynamely, the destruction of the entire pipe-covering simply to 4reach the joint or other connection in the pipe.

It is obvious that the framing of my improved covering may be changed inform to suit any sort of pipe connection without deplied. These clampsare essentially the same as the clamps a before described. Said clampsare joined together in the cruciform arrangement shown by means oflongitudinal connecting-bars formed of two sections it, angular. incross-section and "fastened rigidly together by bolts 11. The ends ofthe respective connecting members it are fastened by bolts is to theends of the respective clamps g. This forms a rigid frame, over which ashield similar to the shield e, but varying in shape to fit the peculiarconnection, may be applied, this shield in turn carrying thenon-conducting covering similar to the covering f.

Fig. 3 shows the invention applied to an elbow connectionwhich is notdifferent essentially from the other forms of the invention. In thisview Z indicates the two clamps which are applied to the respectiveparts of the pipe and which are similar to the clamps in Fig. 2. Saidclamps are connected by longitudinal connecting members m, similar tothe connecting members 6 and h excepting thatthe members m follow thecontour of the elbow-joint. The frame thus supported will carry theshield and covering, as before described.

Fig. 4 shows the application of my covering to a valve casing and headwhich forms the connection between two sections of the pipe. To suchsections of the pipe are applied clamps at, similar to the clamps beforedescribed, and to the crown or head of the valve is applied a clamp 0.Said clamps n are connected together at the bottom of the valve by meansof a connecting member p, similar to the members b, h, and m, but shapedto correspond with the bottom of the valve. The frame a has its ends,-respectively, in connection with the upper ends of the frame n by meansof connecting members 7-, which are constructed in sections the same asthe connecting members previously described and are shaped to correspondwith the general form of the valvecasing.

In all constructions of the framing it forms the support or framework ofa covering which is independent of the covering ofthe pipe-sectionsthemselves and which snugly and completely covers the entire connection,so that the connection-cover may be removed at will without disturbingthe covering of the pipe. Various changes in the form, proportions, andminor details of the invention may be resorted to at will withoutdeparting from the clamps, longitudinal connecting members extendingbetween them, a shield applied to the connecting members, and a coveringproper applied to the shield. V

3. A covering comprising clamps, longitudinal connecting members joiningthem together, said clamps and connecting members constituting a frame,and a covering proper applied to said frame.

4. A covering comprising clamps formedof.

two sections, adapted to embrace the structure to which the covering isapplied, connecting members joiningsaid clamps together, said clamps andconnecting members constituting a frame, and a covering proper appliedto the said frame.

5. A covering comprising a frame formed of clamps made in two sectionsfastened together, to embrace the structure to which the covering isapplied and longitudinal connecting members also formed in two sectionsfastened together and extending between and connecting said clamps, anda covering proper applied to the frame.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
